Secrets Management Extensions

[mcred]

Initial landing page for secrets management extensions.

TODO:

• Import READMEs from the target repos:
  • AWS Secrets Manager
  • HashiCorp Vault
  • CyberArk PAM
• Create idea portal pages for each extension for feedback.

Question:

• Considering that the HashiCorp vault extension will likely soon be certified by HashiCorp, it likely needs to not be in Lab Status. Should we add a column to say whether or not it's a lab release?
